All organisms must communicate with one another in order to
survive and reproduce.
Bacteria and other microorganisms communicate so they don’t
multiply too much and overcrowd a space, so they know when to reproduce, and
more.
Multi cellular organisms communicate to know the whereabouts of
other organisms, whether they be potential mates, prey or otherwise. They use a
variety of methods to convey their methods. Wolves use chemicals (urine) and
sound (howling) to let other animals know where they and their territory are.
They use sight, sun placement and weather patters to migrate and
navigate so they don’t get lost or can move to an area with a preferable
climate and recources.
Animals such as bears use scents to identify their young, find
food and even to navigate.
The nervous system consists of the Central Nervous System and the
Peripheral Nervous System. The CNS is the brain and spinal chord and the PNS
are all the nerves branching off of them.
A neuron is a nerve cell that receives and transfers a neural
signal. The signal enters the dendrites, which are around the cell body,
transfer through the cell body, goes through the axon and out the axon terminal
and over the synapse and into another cell’s dendrites.
